A map of Texas has the following scale.

1 cm = 50 km

The distance from Austin to Dallas measures 6 centimeters on the map. What is the actual distance ?

56 km

156 km

300 km

600 km

To find the actual distance, we need to convert the measurement on the map to the actual distance using the scale.

According to the scale, 1 cm on the map represents 50 km in reality.

Therefore, if 6 cm on the map represents the distance from Austin to Dallas, the actual distance can be calculated by multiplying 6 cm by 50 km/cm:

6 cm * 50 km/cm = 300 km

Therefore, the actual distance from Austin to Dallas is 300 km.

So the correct answer is 300 km.
